Did you ever swap an ingredient in a recipe with something similar, hoping nothing would change? But you found the recipe tasted weird or it failed completely? Not every ingredient is interchangeable and not every food item is similar, even if it looks that way. Take for example, baking soda -- you can't just swap it with baking powder because you'll get a flat cake. Ever wonder what's the difference between ginger ale and ginger beer, or seltzer and club soda? And why are there two kinds of cocoa powder on the supermarket shelf? To learn the difference between these examples and more, see the slideshow below.
